Given numbers are 418,674,798,636
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 418,674,798,636 is 313567716.
Find LCM of 418,674,798,636 with Prime Factorization
| 2 | 418, 674, 798, 636 |
| 3 | 209, 337, 399, 318 |
| 19 | 209, 337, 133, 106 |
| 11, 337, 7, 106 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 19 x 11 x 337 x 7 x 106 = 313567716
Therefore, the lowest common multiple of 418,674,798,636 is 313567716.
LCM formula is LCM(a1, a2, an) = (a1 x a2 x an)/{GCF(a1 x a2 x an) x common factors}
Firstly, we have to find the product of all the numbers.
418 x 674 x 798 x 636 = 142986878496
Then, let us find the GCF of these five numbers. To do so, we have to list down the factors for each number and choose the highest factor that is in all of the lists.
418 : 1, 2, 11, 19, 22, 38, 209, 418
674 : 1, 2, 337, 674
798 : 1, 2, 3, 6, 7, 14, 19, 21, 38, 42, 57, 114, 133, 266, 399, 798
636 : 1, 2, 3, 4, 6, 12, 53, 106, 159, 212, 318, 636
2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 418,674,798,636, is 2.
Now, the common factors can be found like this.
418:2x 11x 19
674:2x 337
798:2x 3x 7x 19
636:2x 2x 3x 53
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 2x 3x 19 = 228
Therefore, the value for common factors is 228.
Now that we have all the elements of the formula, we can plug them in to calculate the LCM.
LCM(a1, a2, an) = (a1 x a2 x an)/{GCF(a1 x a2 x an) x common factors}
LCM = 142986878496/(2x228)
LCM = 142986878496/456
LCM = 313567716
Thus, we can understand that the LCM of 418,674,798,636 is 313567716.
